Sunday evenings: free Jarana dancing in Parque de las Palapas starting 7pm. Traditional Yucatecan folk dance, locals teach visitors basic steps. Families bring picnics, marimba bands play until 10pm.

El Rey ruins: Only Mayan site actually in Hotel Zone (65 pesos entry). Walk from most hotels, watch iguanas sunbathe on 1,200-year-old stones. Perfect sunset photography without tour group crowds.

Many hotels do authentic Mayan fire ceremonies at sunset - Hotel Xcaret, Moon Palace. Non-guests can watch from beach bars during happy hour.
